ABSTRACT
Obesity has become major worldwide health problems. Serotonin (5-hydroxytryptamine; 5-HT) is a neurotransmitter that contributes to the regulation of many physiological processes and abnormalities of the serotonergic system have been implicated in the pathogenesis of obesity. 5-HT2A receptor is belongs to Gprotein coupled receptor (GPCR), expressed widely throughout the central nervous system (CNS). Hypothalamic 5-HT2A receptors might have a role in the regulation of feeding and energy homeostasis. 5-HT2A receptor gene expression was increased in association with obesity. 5-HT2A receptor antagonism increases expression of adiponectin and decreases plasminogen activator inhibitor 1 (PAI-1) expression via the 5-HT2A receptor signaling cascade. Recently, development of 5- HT2A receptor antagonists as a novel therapeutic strategy for obesity and associated comorbidities has been the focus of much interest. Here, we describe the role of 5- HT2A receptor in pathogenesis of obesity.
